NUTr-MACHNE.

' To all it may iami-J I scribed and claimed.

' plan view on a l\ ,Be'itknown that I, FREDERI LAoKNER, residing. atPittsburg, in thecounty of Allegheny and Stateof Pennsylvania, a citizenof the ,Unitedfitzites, have. invented ordiscovered certain new v larid{useful Improves ,mem n Nut-Machines of which improvementsthefollowing,is a specification.

certain improvements in the manufacture of nuts, washers, etc., and hasfor its object a construction and combination of mechanism wherebyablank may be artially severed from a bar, partially punc ed and shaped,then com letely severed from the bar and the unchmgand shapingcompleted. I

T e invention is hereinafter more fully de- In the accompanying drawingsforming a part of this specification, Figure 1 is a to plan view of myimproved machine; Fig. 2 1s asectional elevation on a plane indicated bythe line II-II Fig. 1; Fig. 3 is a sectional lane indicated by the lineI-III Fig. 2; ig. 4 is a side elevation of the machine.

b In the practice of my'invention the bar, a, is fed forward bymechanism hereinafter described against: a movable 'stopl, the posi-'tion of said sto beingec centr c to the axis of'the bar when eing fedasshown in Fig. 15. As soon as the end of the bar comesin contact with thestop, the slide2having a shear edge, b, is moved forward to the left inFi 1 partially severingthe endportion of the ar was shown in Fig. 16.38y thr partial seven ing and .simultaneousilateral movement of pSpecification of Letters Patent. application filed February a, 1906'.Serial No. 300,122.

The invention described herein relates the blan slides 2 and 3, and intothe shaping matrix 6.

By this movement of the plunger and blank v Patented June a, 1908.

i the partially severed section 0, the latter is moved against the endof a slide 3 as shown inFig.-16. ,7 I

ltwill be observed by reference to Figs.'15 and 1.6 that theo erativeends of the slides 2 and 3 are recesse or provided with matricescorrespondingto the cross sectional shape of the nut to beproduced, andthat when the slide 2 is shifted as above stated to the left, these twonotches or recesses form a complete matrix correspondin or approximatelycorrespondin in shape an dimensions to the nut to be produced. whentheportion c has been partially severed and shifted as shown in Figs. 16and 17, a punch 4 is moved forward through the movable stop 1, therebpartially perforating the portion 0.. It w' l e observed that-in thispunc'hing'o eration the portion c is backed 'up in part at east bythe-rod a, the axis of the punch while eccene tric to the axis of therod, is in line or ap roximately in line with the surface of the ar ormay be slightly within the perimeter thereof. In addition to the su portthus furnished by the end of the bar a t e portion 0 is alsosupportediduring this punching operation by the movable gripping member5 which is oper ated as hereinafter described.

'- After the punch 4 has completed its forward movement, the movablestop is given a slight inward movement so as to partially compress andlaterall splread the portion a causing it to complete y lthe matrix inthe slides 2 and 3, if the rior punching operation has not affectedtfiat purpose, as shown" in Figs. 17 and 18. After the withdrawal of thepunch and plunger the slides 2 and 3 are moved to the right as shown inFig. 19 there by efiecting a com lete-severance of the or.- tion 0 fromthe ro and its transfer into ine with the final shaping matrix 6. Assoon as the slides have reached theposition shown in Fig. 19 a lunger 7is moved forward, forcing ii 11 from between the blades or the thin wallleft by the artial punching operation previously descri ed, is removed,the blank being forced over a stationary unch 8 having its operativeportion arrange within the matrix 6. The metal removed by this punchingoperation is forced into an opening or passage through the plunger 7. Inadditionfto thus completing the punching opera 'tion, the plunger 7 isgiva en sufficient movein contact with t 6 end portion of the bar awhich has been fed forward against the movable stop 1, subse uent to themovement of the slide 3 to the le t. The movement of the slide 2continues thereby partially severing the endportionofthebar, and forcingsuch partially severed portion against the sha ing ortion of the slide 3as heretofore described.

uring this movement of the slide 2 to the left an opening 9 in the slidein the rear of its shaping edge, is brought into line with the matrix6-and the previousl --shaped or finished nut is forced out of sai matrixthrough the opening 9 in the slide 2 by a plunger 10 whose inner endforms the back wall ofthe shaping matrix and through which the punch 8extends. v

Having thus described the operation of'the several parts directlyoperative upon the bar and blank to produce a nut or washer, I will nowdescribe the mechanism whereby these parts are properly shifted toeflect the desired result. The slides 2 and 3 are adjustably secured asshown in Fig. 2, to theheads 11 and 12 secured to yokes 13 and 14surrounding the cams 15 and 16 on the shafts 17 and 18, which arerotated in any suitable manner known in the art. These cams are soconstructed that the slide 3 will move to the left in advance of theslide 2 and will then rest until the slide 2 has been moved forward asheretofore described to effect the partial shearing of the end portionof the bar. After this partial shearing has been eifec ed the slide 3will remain stationary and t e slide 2 will come to a rest both slidesbein stationary during the partial punchingan shaping effected by thepunch 4 and plunger or stop 1. The cams 15 and 16 will then operate inunison to move the slides 2 and 3 to the right thereby completelysevering the I ortion c from the bar and carrying the b ank into linewith the matrix 6. The cams then hold the slides in this position untilthe plun er 7 has moved forward f orcingtheblank om between theslides'and into the shapin ma trix. The cam 16 will then shift the side3 back to its position to theleft and the cam 15 .will hold the slide 2stationary until the,

punch 7 has moved inward and returned to the position shown in Figs. 16,17 18, 21 and 22, when the cam 15 will again shift the slide 2 t0 theleft. The blocks 11 and 12 p are mounted in suitable guideways in aframe 19 shown in Figs. 1, 2, 12,13 and 14, which'is adjustably securedas indicated to upwardly projecting portions 20 and 21 on the bed of themachine. By reference to Figs. 2 and 3 it will be seen that although Ihave described the cam 16 as a single cam, it is preferred to form thesame in two independent sections for convenience in the manufacture andadjustment.

The plunger 1 is secured in a head 22 car-. ried by the sliding block 23suitably recessed .to form a yoke for the cam 24 on the shaft '25 asshown in Fig.5. It will be observed that this cam is constructed to givethe desired back and forth movements whereby the plunger is laced inposition to op)erateas a sto for the -movement of the ar afand shiftedaway from such position and is also provided with a small projection26whereby the slight inward-movement is given tothe plunger to effectthe compression ofthe tion a after it has'bee'n'partially punched asheretofore described.

The punch 4 which as heretofore stated operates through the plun er 1 issecured to a sliding block 27 mounte in suitable ways in the bed of themachine and constructed to form a yoke for the cam 28 on the shaft 25,

as shown in Fig. 6.

The feed mechanism for shifting the rod consists of a gri ping devicehereinafter described, mounte upon a slide 29 arranged in suitable waysin the bed of the machine, and adapted to be moved back and forth bymeans of a cam 30 on the shaft 25, operating within a yoke consisting ofmembers 31 and 32, and connected by rods 33 to the slide 29, as clearlyshown in Fig. 8. The cam 30 is provided with an adjustable section 34and one of the members of the yoke as 32, is adjustable towards and fromthe other member on the rod 33 so as to permit an adjustment orregulation of the amount of feed lmparted to the rod 0. dependent u onthe dimensions ofthe nut or washer to e produced. The slide 29 isrovided with suitable uide-ways 35 for the s lide 36, carrying movablegripping member 37. The stationary grip ing mem ber 38 is secured to orformed on t e slide 29 as shown in Fi 11. engagement of the grippingdevices with the bar or rod 0. it is .pre erred that the blades shouldbe secured to the members 37 and 38 of the gri pers,so that the, willbite into the bar or ro when a feed is esired. By reference to Figs. 1,3 and 10 it will be seen that the grip er 37 is secured to an extension39 of the s ide, having an enlarged slot therein for the passage of thebar a. When it is desired to release the bar from the rippers the slide36 is moved to the left there y bringing a portion, 39, of the wall ofthe slot in the member 39 against the bar or rod and shifting it so asto 'releaseit from the blade of the member 38 on the grip er. In casethe bar or rod should follow t e member 37 in its movement to the left,it will be drawn a ainst a stop 40 on the slide 29 and prevente fromfurther movement with the member 37, thus In order to insure afirmreleasing the latter from the rod. The slide 36 is formed on orconnected to a yoke 41 in which operates a cam 42 on the shaft 18, saidcam having an adjustablesection 43 to permit of the use of the grippersin connection with bars varying diameter.

When the bar or rod is fed forward, it passes through an opening 44 inthe frame 19 and in order to hold the portion of the bar or rod adjacentto the part to be severed therefrom, suitable gripping mechanism isemployed consisting of a p ate 45 secured within a recess in the frame19 and a movable gri ping member carried by a slide 4'6 movab e in waysin the frame 19. This slide is connected to or form'edon a oke 47 inwhich operates a cam 48 ,on the sliaft 18, as shown in Figs. 3 and 9.While the gripping block '5 may be secured ito the slide 46 in anysuitable manner, it is referred that it should be formed with ajfiig 49projecting through an openin in the fslide as shown. The plate 45 whichas formed therein the final shaping matrix 6'is adjustably securedwithin the frame 18 by means of blocks 50 and wedges 51 as shown inFigs. 2 and 3.

The plunger 7 is secured in a head 52 formed on or secured to a -yoke 53mounted in suitable ways on the bed of the machine and inclosin a cam 54on the shaft 25, where by the plunger is moved towards and partiallyinto the matrix 6 as shown in Fig. 20, forcing in its movement, theblank from between the blades 2 and 3 as heretofore described. slide 55mounted in ways in the bed of the machine is connected by rods 56 to theyok so as to be moved thereby. will be observed by reference to Fig. 7that whenthe oke moves to the left to force the plunger in o the matrix,motion will be communicated; to the slide 55 through springs'57, wherebythe slide will be moved against an adjustable stop 58 and thatthereafter the movement of the plunger and yoke will be independent ofthe slide, he compression of the springs permitting ofcsuchindependentmovement. To the slide is secured the block 10 whose inner end-forms theback wall of the matrix 6. By the primary movement of the yoke thisblock 10 isdrawn to pro er position in the matrix and is held fromurther movement by the stop 58. When the yoke moves to the right theplunger 7 will be first withdrawn from the matrixand there after theslide and block will move with the plunger thus forcing the completednut out of the matrixand through the opening 9 in the blade It will beobserved that the cam 54isiso constructed as to permit the yoke andparts operated thereby to rest after the plunger has been withdrawn fromthe matrix, thus affording time for the slide 2 to be shifted asheretofore stated to bring the .o ening 9 into alinement with thematrix.

e punch 8 issecured to a screw 59 passing erance of the bar or rod.

through thestop 58. In Fi 23.1 have shown a certain modification o mymachine in which the slides 2 and 3 are formed integral with each otherand the preliminary shaping matrix formed in the edges, the con-.

struction heretofore described of the slides being made with integralwalls in single slide 60. In this construction a single cam 61 on theshaft 18 is employed, said cam being suitably constructed to impart-thedesired motions to the slide 60. This cam should be constructed to allowthe slide to remain stationarywhile the plunger 7 operates and thenmoved \to the eft after the withdrawal of the plunger to bring thepreliminary shaping matrix e into alinement with the rod (1.
